LG Dryer Error Code nF

The nF code means the dryer's Wi-Fi feature has not been registered through the LG ThinQ app. It is a status notification, not a mechanical or electrical fault. The dryer will continue to operate all drying functions normally. Registration through the ThinQ app and a power cycle will clear the code.

No, the nF code does not indicate any safety issue. It only reflects that the Wi-Fi registration step has not been completed. All heating, motor, and safety components on the dryer function independently of the ThinQ registration status.

In most cases there is no cost at all, since the fix requires only downloading the free LG ThinQ app and completing the registration steps. No replacement parts are needed. If the code persists after registration and a power cycle, a service call to inspect the Wi-Fi module or control board could cost anywhere from 75 to 200 dollars depending on your location and the technician's findings.

Download the LG ThinQ app on your smartphone and log in or create an LG account. Follow the in-app prompts to add and register your dryer. Once registration is confirmed in the app, unplug the dryer from the wall outlet, wait a few seconds, and plug it back in to allow the control board to update its connectivity status.

A basic power reset alone will not clear the nF code because the code returns whenever the dryer detects it is not registered to a ThinQ account. You must complete the app registration process first, and then perform the power reset by unplugging and reconnecting the power cord to allow the change to take effect.
